The hack is located here:  https://gitlab.cee.redhat.com/insights-platform/fakamai-assets-server/-/blob/master/conf/generate_index.py#L10

A "Preview" entry needs to be added to this file https://console.redhat.com/config/releases.yml to fix this correctly as things are currently.  Other components within the fakamai impl use this file, but this file is deprecated according to the plat-ex folks.  So we might need to create this file within the fakamai code base and just manage it ourselves.

I believe the releases.yml file is located here in github https://github.com/RedHatInsights/cloud-services-config/blob/ci-beta/releases.yml

We also need to remove the "Beta" entry.
